 JAXA generated a global DEM slash DSM and ORI using archived data from Prism on Allows, which had a spatial resolution of 2.5M in the nadir-looking radiometer and achieved global coverage. The agency conducted calibration to improve accuracies and validate high-level products such as DSM and ORI. Data processing strategies were developed for hardware and software to achieve project aims, and an automatic DSM slash ORI processing software was introduced with test results.
